Description

Technical Field

[0001] The invention belongs to the technical field of pallet tooling, and in particular relates to an automatic changeable pallet adaptable to multiple transmissions. Background Art

[0002] On the automobile gearbox assembly and testing line, pallets, as a transportation medium for gearbox products, not only connect all the processes on the entire production line in series, but also carry product information for easy reading and identification, and provide real-time feedback of product information. Currently, the industry's pallets include fixed pallets and mother-and-child pallets.

[0003] Fixed pallets are specific, that is, each pallet is for a specific gearbox product. Because its positioning and support room are fixed, it cannot be compatible with other products with different positioning and support. The only way to achieve compatible products on the production line is to replace the pallet. Later, the mother-and-child pallet was developed for compatible products. That is, the pallet base body is fixed as the mother pallet, and sub-pallets for different products are used to carry the gearbox products. When replacing different products, the sub-pallet needs to be removed from the mother pallet, and the corresponding sub-pallet needs to be replaced and re-fixed on the mother pallet. The mother-and-child pallet has achieved compatible products in a certain sense, but it has some disadvantages: 1. The number of sub-pallets needs to be the same as the mother pallet, and the cost increases with the increase of sub-pallets. 2. Sub-pallet replacement requires manual operation, which is time-consuming and labor-intensive. In addition, due to the beat requirements, the line needs to be stopped every time a sub-pallet is replaced, resulting in unsmooth production and affecting efficiency. Summary of the invention

[0020] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0021] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0022] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0023] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0024] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0025] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0026] Beneficial effects of the present invention:

[0048] The height-angle double-displacement support member 5 includes a third support tube 51 fixed on the tray body 1, the upper end of the third support tube 51 is overlapped with a third adjustment block 52, the upper end of the third adjustment block 52 is fixed with a third support block 53, the lower end of the third support block 53 is fixed with a third quick-change shaft 54, the third quick-change shaft 54 ​​passes through the third adjustment block 52 and extends into the third support tube 51, the third quick-change shaft 54 ​​is sleeved with a third stop gasket 55 and a third compression spring 56, the third stop gasket 55 is clamped in the third support tube 51, the lower end of the third quick-change shaft 54 ​​is fixed with a third stop block 57, the upper end surface of the third support tube 51 is evenly distributed with three fifth protrusions 58, the lower end surface of the third adjustment block 52 is evenly distributed with three sixth protrusions 59, the upper end of the third support block 53 is fixed with a second fixing rod 8, and one end of the second fixing rod 8 is fixed with a support rod 81.

[0049] The method for using the pallet of the present application is mainly to change the shape by adjusting the vertical height adjustment support 3, the height adjustment rotation positioning member 4 and the height angle double displacement support 5 to be compatible with different gearbox products, and the shape change operation is performed by a robot arm to achieve automation.

[0050] Specifically, the vertical height adjustment support member 3 is changed by clamping the tenons on both sides of the first support block 33 with the claws of the mechanical arm, and then lifting it upwards. The first quick-change shaft 34 drives the first adjustment block 32 to disengage from the first support tube 31 and then rotate it, so that the first adjustment block 32 changes the contact surface and then falls back on the tenon and tenon of the first support tube 31. The first quick-change shaft 34 and the first adjustment block 32 ensure that the contact surface is flat under the action of the compression force of the first compression spring 36 and its own weight, and the height change is achieved due to the change in the surface of the first adjustment block 32 and the first support tube 31.

[0051] Specifically, the height adjustment rotating positioning member 4 is changed by clamping the tenons on both sides of the second support block 43 with the claws of the mechanical arm, and then lifting it upwards to drive the second quick-change shaft 44 to drive the second adjustment block 42 to disengage from the second support tube 41 and rotate it, and rotate 180° to adjust the position of the positioning pin 71, so that the second adjustment block 42 changes the contact surface and then falls back on the tenon and tenon of the second support tube 41. The second quick-change shaft 44 and the second adjustment block 42 ensure that the contact surface is flat under the action of the compression force of the second compression spring 46 and its own weight, and the height change is achieved due to the change of the matching surface between the second adjustment block 42 and the second support tube 41.

[0052] Specifically, the height and angle double-displacement support member 5 is changed by clamping the tenons on both sides of the third support block 53 with the claws of the mechanical arm, and then lifting it upward. The third quick-change shaft 54 ​​drives the third adjustment block 52 to disengage from the third support tube 51 and then rotate it. After rotating 60°, the third adjustment block 52 is allowed to fall back on the tenon and groove of the third support tube 51 after the contact surface. Under the action of the compression force of the third compression spring 56 and its own weight, the third quick-change shaft 54 ​​and the third adjustment block 52 ensure that the contact surface is flat. The height change is achieved due to the change of the matching surface between the third adjustment block 52 and the third support tube 51, and the support angle change is achieved due to the change in the position of the tenon and groove of the third adjustment block 52 and the third support tube 51.
